12 years ago I successfully recovered after stage 4 cancer at the Base of the Tongue with secondaries in the lymph nodes. 3 years ago my swallowing deterioated and is now quite reduced still. However I mange quite well except for reduced saliva which leaves me constantly thirsty. I am now being investigated for a very small area on my lung as being an early stage cancer. I am dreading the thought of surgery and having to fast with having no water. This would be torture for me as I occasionally do have a problem swallowing the saliva at night time. Can you advice me at all? Many Thanks Pat
